What is the difference between EVM equivalence and Ethereum equivalence
Updated
EVM equivalent: The rollup is nearly identical to L1 Ethereum from the dapp developer perspective. OP Mainnet has been EVM equivalent since the OVM 2.0 upgrade on November 11th, 2021.
Ethereum equivalent: The rollup is nearly identical to L1 Ethereum from the protocol developer perspective. With the Bedrock upgrade (June 6th, 2023), the difference is very small, mostly dealing with communication between layers. The execution-layer functionality is nearly identical. The consensus layer has to be very different in a rollup, but we are isolating that functionality into a component called op-node.
